Noisy Dometic Refrigerator Fans

Prior to our current 5TH wheel RV we had a Dometic refrigerator in that unit and it exceeded our expectations. Everything in the refrigerator was cool or cold and the temperature remained in the 33-34 degrees range on the hottest of days. NO FAN NOISE

Last November we purchased a new 5TH wheel RV and this unit also has a Dometic refrigerator model DM2862lbFX and it does maintain the temperature in the 33 to 34 degree ranges also. But on hot days evidently there are two fans in the unit that are activated when the temperature reaches a certain level. These fans continue to run well into the night and we can even hear them in our bedroom. Needless to say they are really noisy when one is setting in the living room area. So I took the RV to the dealer told him about the fans being extremely noisy and the RV dealer replaced the fans. Well the new fans are still very noisy with a medium to upper pitch sound. Again easily heard in our bedroom during the night until they shut down.

Is there a solution to the noisy fan problem? I can not understand how Dometic would let a product like this be marketed to the RV industry. Has anyone else experience the noisy Dometic Fans in their unit.
  • Just wondering...are you sure they are refrig fans and not the converter cooling fan that you are hearing?
  • We also had the noisy fan issue with our Cougar
    Any camper models with the frig in the slideout
    will have no venting to the roof
    So the frig unit is cooled by these fans
    and are activated on a hot day by a thermostat

    For us, having the frig in a slideout was new so we went from
    no frig noisy at all to the hi pitched fan running

    My dealer told me that this noisy was normal for Dometic

    I didnt believe it so I contacted Dometic
    They responded with telling me the fan should not be noisy
    Told me the correct order # to give to my dealer and have him replace the noisy fan

    The dealer ordered the new fan, replaced the old fan
    and all is good now

    Hope this helps you
  • I also have a noisy temp activated fan but doesn't really bother me. I did some research and found that some have replaced the cheap OEM.fans with simple computer fans. Apparently, the use the same voltage and are silent. They are also quote inexpensive. I also read that they are located in a very difficult spot to remove and replace.
    I'm thinking of changing mine someday soon.
  • My Dometic (not in a slide) has a fan located out of reach, high in the cooling tubes, that runs for a minute every couple minutes. The fan blows directly on the thermostatic switch, causing short runs. It sounds like it is solidly mounted to the cooling tubes, which make a great resonator - drives me nuts! Some day I will pull the fridge, rubber mount the fan, and move the thermostatic switch out of the airflow. Meanwhile I installed 2, near silent, 12v computer fans hanging on shock cord, pointed up the stack. It helps. Check CFM and DB ratings - all fans are not created equal.
  • Dealer replaced our noisy refer fan
    Under warranty. New fan can barely
    Be heard. Don't have to turn tv up
    When fan kicks on any more.

    Sure wish I would have had our fans replaced... Was told by the dealer that noise was normal for a refer mounted in the slide.
  • The fan can be replaced with a computer fan - I added a second fan and the original one runs less.

    Ours has a high pitch tone too.
  • Did the computer fan mod on a dometic fridge today. Two 120mm computer fans from best buy. $10.00 each. Works great and very quiet.
  • Yeah, but what about the blue light? On a serious note I did complain to Dometic and they are sending me a white replacement interior light. I have to figure out whether I want the dealer to try and fix the fan noise or (likely) deal with it myself.
  • Our fan was okay for a year or so but started making a high pitched noise. I searched online and found some waterproof computer-type fans and replaced the one that was there with two waterproof fans. Now there is no noise and the fridge works like a champ.
